Abstract
The invention relates to an energy recovery system of a railway vehicle. A friction strip is arranged at the lower part of a carriage; one end of a swing arm is hinged with a support seat A fixedly connected to the ground; a first rotating assembly comprises a friction wheel, a driving wheel and a first transmission shaft, and the first transmission shaft is rotatably connected with the other endof the swing arm; the friction wheel is matched with the friction strip; a base of a hydraulic cylinder is hinged with a support seat B fixedly connected to the ground, and the end part of a piston rod of the hydraulic cylinder is hinged with the middle section of the swing arm; a second rotating assembly comprises a driven wheel, an output gear and a second transmission shaft, the second transmission shaft is rotatably connected with a support seat C fixed on the ground, and the second transmission shaft and a hinge point of the swing arm and the support seat A are coaxially arranged; the driven wheel is in driving connection with the driving wheel; and an auxiliary gear is arranged on one side of the output gear and is meshed with the output gear, and the end part of a rotating shaft inthe center of the auxiliary gear is connected with a generator through a clutch and a gearbox in sequence. The system can effectively recover energy of the railway vehicle at the stage of braking whenthe railway vehicle enters a station.
Description
technical field [0001] The invention relates to the technical field of rail transportation, in particular to an energy recovery system for rail vehicles. Background technique [0002] With the continuous development of the city, the transportation mode is also constantly improving. Rail vehicles such as light rail and subway have become the main transportation mode in many cities. While improving urban traffic operation capabilities, rail trains have also brought about a sharp increase in energy consumption. Therefore, related energy-saving technologies such as train energy-saving operation control and regenerative braking have received great attention. During the braking process of rail vehicles, a large amount of kinetic energy will be converted into heat energy, which will cause serious wear and tear on the braking system while wasting energy. At present, relevant technologies have been disclosed, and a battery is installed in the rail vehicle to recover the braking ele...
